FEATURES

Tactile. Clicky. Backlit
The mechanical keys are tuned to be tactile and “clicky”, reminiscent of the vintage
typewriter. Each mechanical switch is customized so that the backlight LED is in
the center of each key, allowing the keyboard to illuminate evenly and beautifully.
Genuine & Luxurious
Genuine top plate. Leather and wood has always been associated with high-end
customized goods and exclusiveness. It reflects taste, craftsmanship, and culture
while emitting a unique charm that inspires.
Supports Both PC & MAC Layouts
Both Windows and Mac layouts are supported. When Mac mode is selected, simply
pop on the included Mac-specific keycaps.

SETUP
Setting Up
The Retro Classic BT is a very versatile keyboard that supports both MAC/PC and can be
connected wirelessly via Bluetooth or wired via USB. The operating system selection and
interface mode switches are both located on the back side of the keyboard.
Pairing the Keyboard in Bluetooth Mode
Switch the keyboard to BT mode. The mode switch is located on the back side of the
keyboard.
Put the keyboard in Pairing Mode by holding down (FN) key and the ( - ) key on the
number pad. Hold down these two keys for a few seconds until the blue LED (Marked
“W”) changes from a quick flash to a slow continuous flash. The keyboard is now in
Pairing Mode.
On your Mac, navigate to ‘System Preferences’ and select ‘Keyboard’. Next, click on
‘Set Up Bluetooth Keyboard’. For Windows 10, go to Bluetooth Settings and select ‘Add
Bluetooth or other device’.
Once the setup wizard finds ‘AZIO Retro Classic BT’, click on ‘Pair’.
Once pairing is successfully completed, the blue flashing LED (Marked “W”) will stop
flashing. The keyboard is now ready for use.

SETUP
Charging the Keyboard
Battery Life
When the battery is less than 20%, the status indicator LED labeled ‘S’ will start blinking in
red. Plug the included USB cable into the keyboard and a USB port or a USB charger. The
same LED will stop blinking and light up a steady red, indicating the keyboard is charging.
Once fully charged, the red LED will turn off. Charging a completely drained battery to full on a
USB 3.0 port will take approximately 8+ hours due to its large power capacity. Actual charging
time may vary depending on the power output of the charging source. The keyboard can only
be charged under BT or USB mode.
This keyboard uses an industry leading 6,000mAh Li-ion rechargeable battery and will only be
used when in Bluetooth mode. With the backlight off, the keyboard can last for about 7 months
to a year on a single charge. With the backlight on, depending on intensity, can last for about
1 to 3 months on a single charge. Under Bluetooth mode, the keyboard backlight will turn off
after 5 minutes of inactivity to conserve battery. After an hour of inactivity, the keyboard will
enter sleep mode. Press any key to wake up the keyboard and reestablish connection. The ‘W’
status indicator LED may flash blue during re-connection and stop flashing once connection is
reestablished.
